| Claus, I think to myself that I should probably have those parts, because some day I may need them, but then reality sets in. If I were to take them, then in about 20 years, my kids would be placing an ad very similar to yours! LOL. Darrel |

| Gary I think you are talking about the 8.2L V8 Turbo Diesel, a Detroit 6-71 is totally different,2 stroke, 6 cylinder,blown motor. |

No this is an in line 6, detroit, I thought it was a 6-71. He has it on the farm and used it to haul wheat, we were going to use it to haul some dirt a few month ago and the water pump leaked all of the coolant out. Not sure of the year of the truck, but it is a detroit about a 80 something year model hauls about 18,000 lbs.

Yeah GM ran them in tons of trucks.....seeing how GM built the engines lol. 6-71 were inline 6's and I think the 6-53 was a V6 I'm pretty sure.

Actually I believe you could get a 71 in either inline6 or V6, believe they had 3, 4, 6, 8, 12 and 16 cylinders. I believe the 53 and 92 were much the same way. Gary, as for the water pump all I can tell you is give my Dad a call. |

I have a '63 Chevy C80 with a 6V53, was used to haul cars from the factory. Used it myself as a farm truck. Now it has had a building setting on the flatbed. May get the building on a foundation this year, it's on the list.

You can get most of the 2 stroke in an inline or V configuration
6-71 is an inline six cylinder with 71CID/per cylinder
6v-71 same as above only a v6 instead of inline
12v-71 would be a V12 with 71CID/per cylinder, or in basic terms, 2 6V-71 hooked together ------------- Experience is a fancy name for past mistakes. "Great moments are born from great opportunity" 1968 D15D,1962 D19D Also 1965 Cub Loboy and 1958 JD 720 Diesel Pony Start |

| 12V92's are 2 6's bolted together using 4 heads and valve covers just as the 16V92's are 2 8V's bolted together. 12V71's I have seen are one piece block and use inline 6 heads and valve covers but the 16's are 2 8V's like the 92's. |

You have to be careful on the sleeves on a 71 series, they are NOT all the same size externally. There was a factory ink stamp on the sleeves as they shipped them new, a mark toward the top of the sleeve was a tad bit light on dimension while a mark to the lower was a tad bit heavy. A 'Standard' bore sleeve could be +/- .002, a .010, .015, .030 was the same for dimension stability. I overhauled a great deal of the 6L-71, 6&8V-92 and a few 6V-53 in my career and only the 71 was a dry fit sleeve, the other two being wet liner around the combustion area. If you install a 'loose' sleeve, one that falls easily into the bore it will fail at the intake ports under load or not transfer heat very well and gall piston to bore then tear the sleeve in half at the ports(can ruin a block). If you have to drive them in they will gall severely in the first few hours of operation and then smoke the crank from excess pressure. Been there, done that with too many guys trying to OH their own on the cheap. We used a Sunnen Hone to fit the liner bores for the sleeves to fit a snug slip fit from top to bottom and required a intake port tool pusher to bring them back out. I have several engines I OH'd years ago still plodding the backroads, most are not quality equipment enough for interstate anymore but set up just as described above. I still have my liner stuffers(put pistons in from bottom of sleeve) to load sleeves/piston/rod at same point of time, for 92,71 and 53 engines. Did OH a few 110's but too big and expensive to buy my own equipment, used a friends but he has long passed and the tools now gone. |

| Those liner stuffers are near a must.Would be very tricky trying to install with a plain jane ring compressor.GM also marked the 92 liners for flange thickness in a similar fashion(ink mark location). Lotta people had bad things to say about the 'ol 2 cycles but most were a result of the people who worked on them that didn't know what they were doing. More to it than meets the eye when setting rack and timing too. |
